SPECIFICATION fOlmlng' 138.115 Of LetteIS Patent N0. 694,686, dated March 4, 1902.

Application tiled DecemberZ, 1901." Serial No. 87,255. (No model.)

To @ZZ whom t may concern:

Be it known that I, MILTON Z. S'IMs, a citizen of the United States, residing'at Aurora, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Brake-'Wheels, of which the following isa specification.

This invention relates particularly to that class of brake-Wheels which are termed tipover wheels, and particularly tothe construc-` tion and arrangement of the parts by. which the brake-wheel may be held in operative position so as to be rotated in a horizontal plane and thrown or folded over into a vertical plane and out of position, as will more fully hereinafter appear.

The principal object of the invention is to provide a simple, economical, and efficient foldable0 brake wheel Aand shaft vof such construct-ion and arrangement that the brake'- wheel may be held in operativeposition so as to rotate in a horizontal plane or folded over into a vertical plane and out of operative position. l i

Further objects cf the invention will appear from an examination of the'drawings and the following description and claims. 4

The invention consists principally -in a brake-shaft and brake-wheel foldably secured together, in combination with springmechanism for yieldingly holding them in their dif ferent positions. l

" The invention consists-,further, in atipjover brake-wheel inwhich there is combined a brake-shaft, a brake-wheel pivotally secured thereto, and spring mechanism securedt-o the brake-shaft for yieldingly holding the brakewheel in its dierent positions.

The invention consists,further, in a tipiover brake wheel in which there is combined a brakeshaft having a bifurcatedend, a brake- Wheel, a'stud upon which such brake-wheel is vestibule portion thereof.

` spring secured to the brakelshaft andprovided with a free end, forming a recesstovengage the angular portion ofy the brake-Wheel stud and yieldingly hold such wheel in its different positions.

The invention consists, further and finally, in the features, combinations', and details 'of construction hereinafter described and claimed. vIn the accompanying drawings,Fig ure lis a plan sectional view of two passenger-coaches, one provided with anordinary platform and the other with a vestibule-platform, coupled together', showing 1n yimprovements attached thereto in operative and inoperative positions; Fig. 2, an end View of a portion of a passengeri coach provided with a brakewheel constructed in accordance with these improvements; Fig.'3,an enlarged elevation, partlyin section,

- of a brake shaft and wheel constructed'in accordance with these improvements, the full lines showing the parts in operative position and the dot-ted lines'showing the brake-wheel in its inoperative position; Fig. 4, a perspective view of the brake-wheel stud, and Fig. 5 la perspective view of the upper end of the brake-wheel shaft.

-Inthe art to which this invention relates it is Well known that ordinary passen ger-coaches are provided with brake-wheels attached to vertical brake-shafts in such a manner ithat such Wheels must rotatein a horizontal plane. The principal objection to this arrangement is that when coupled with a vestibule-coach the brake-wheel is liable to interfere with the It is also well known that when this class of cars is coupled with vestibule-coaches it is quite common to remove the brakewheel from its connection with the brake-shaft landl hangV it over the `same and ont of theway, which. is not only objectionable' from the factof its having to be removed, but, further, in that it cannot always be readily and quickly pnt into position for operative use should occasion require. It is further well known that when the ordinary brake-wheel is in position on an ordinary coach it interferes with the loading and unloading of passengers, those getting on the carquite often striking their garments and persons against the brake wheel, thereby causing them sometimes considerable damage and annoyance.

The principal object of this invention,there fore, is to provide a brake-wheel of such construction as to be foldable into operative and inoperative position quickly and readily whenever occasion requires or necessity demands.

In illustrating and describing these improvements I have only illustrated and described so much as is old, taken in connection with what I consider to be new, as will properly disclose the invention and enable those skilled in the art to practice the same, leaving out of consideration other and Wellknown elements which if illustrated and described herein would only tend to confusion, prolixity, and ambiguity.

In constructing a brake-wheel in accordance with these improvements and using it in connection with a passenger-coach a,l provide a vertical brake-shaft b, which is connected at its lower end by means of a chain c with the ordinary braking mechanism, all of which is well known in this art. It will be seen that it is necessary to rotate this brake-wheel in one direction so as to operate the ordinary braking mechanisms (not shown) and permit it to be rotated in the other direction for the release of the same. In order to provide a wheel therefore for operating this shaft and arrange it in such manner as to permit of its being moved into and out of operative position when desired, I provide the brake-shaft with an upper bifurcated end slotted, as at d.

I next take a brake-wheel e and mount it upon a square portion of a wheel-stud f, so that it cannot be rotated independent of such stud, the wheel and stud being held in engagement with each otherby means of a locking-nut g. The lower part of this wheel-stud is provided with a flattened angular portion h, which is perforated, as at z', so that it may be pivotally secured in the slot formed in the bifurcated end of the brake-shaft, as shown in Fig. 3.

In Fig. 3 it will be seen that the brake-wheel is illustrated in full lines and maybe swung into operative position, but, as shown in dotted lines, that it maybe swung out of operative position or folded out of the way. It becomes necessary, therefore, to provide some means by which these parts-the brake-shaft and brake-wheel-may be held yieldingly in engagement with each other, so as to permit them to perform the desired operations and at the same time permit the brake-wheel to be readily and easily moved. In order to accomplish this result, a tension-spring 7c is provided and secured, as shown in Fig. 3, tothe brake shaft. The upper free end of this spring is so formed as to provide a pocket or recess Z, the counterpart of the angular ends of the brake-wheel stud. The construction is such that when the brake-Wheel has been moved into the position shown in Fig. 3 in full lines the wheel will span the angle m of the stud and yieldinglyhold it, with its brakewheel, in operative position. When the parts are moved into the position shown in dotted outline in the same iigure, the free end of the spring engages and yieldingly holds the angle n ofthe brake-stud, thereby holding the parts in their inoperative position and out of the way, all of which will be appreciated by those skilled in the art.

There are many advantages incident to the use of a foldable brake-wheel constructed in accordance with these improvements, as will be seen from an examination of Fig. l, which shows it attached to an ordinary coach, which coach is coupled with a passenger-coach having a vestibule-platform p. In dotted outline in this gure the brake-Wheel is shown in operative position, so that it is not only liable to interfere with the vestibule, but also with the loading and unloading of passengers. The full lines in Fig. 1 show the brake-wheel in its inoperative position and out of the way, while at the same time permitting it to be readily thrown into operative position as occasion requires.

I claim- 1. In a tip-over brake-wheel, the combination of a brake-shaft and brakewheel with spring mechanism for yieldingly holding them in their different positions, substantially as described.

2. In a tip-over brake-wheel, the combination of a brake-shaft, a brake-wheel pivotally secured thereto and a spring secured to the brake-shaft for yieldingly holding the brake- Wheel in its different positions, substantially as described.

3. In a tip-over brake-wheel, the combination of a brake-shaft havinga bifurcated end, a brake-wheel, a stud upon which such brakewheel is mounted pivotally secured in the bifurcated end of the brake-shaft, and spring mechanism for yieldingly holding the brakewheel in its diierent positions, substantially as described.

4. In a tip-over brake-wheel, the combination of a brake-shaft provided with a bifurcated end, a brake-\vheel, a stud upon which such brake-wheel is mounted and provided with a flattened angular end portion pivotally secured in the bifurcated end of the brakeshaft, and a fiat steel spring secured to the brake-shaft and provided with a free end providing a recess to engage the angular portion of the brake-wheel stud and yieldingly hold such wheel in its different positions, substantially as described.

5. In a brake-wheel, the combination of a brake-shaft having a bifurcated end, a brakewheel, a stud upon which such brake-wheel is mounted pivotally secured in the bifurcated end and provided with a limiting-shoulder to bear against the brake-shaft in one position, and spring mechanism' for yieldingly holding the brake-Wheel in its different positions, substantially as described.
